Why won't my L129 breed again?

[PlecoLad-UK]

Hi all. Hoping someone can at least half help. My L129 bred for me 3 times around 8 months ago, since then nothing at all, not even an attempt. Try are in a 18" cube, daily or on occassions every other day 25-30% water changes with cooler water. Feeding consists of live and frozen bloodworm, prima, KB pellets and algae wafers. The only change has been the intro of 3 cory schwartzi as debris was beginning to build up on 'the floor. Could this really have upset them enough to stop breeding?
Thanks

The Cory’s could be the cause,
In the wild it is very rare for any organism to breed uninterrupted and this is taken as the norm.
Your fish have enjoyed a much protected spawning no threats or disruptions.

I would remove the Cory’s.
See if it makes a difference

Try doing water changes at the same temp. Then say once every 2 weeks do a cooler water change and the fish will respond a bit better to it
